What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

What is genetic drift?

Back

Genetic drift is a random change in allele frequencies in a population, which can lead to significant changes over time.

What is co-dominance?

Back

Co-dominance is a genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Front

What is incomplete dominance?

Back

Incomplete dominance is a genetic situation where one allele does not completely dominate another, resulting in a blended phenotype.
